I'm not too sure how these things work but I think Google takes into account keywords used in your source-type thing. Right now elementsthegame.com has this:
<META NAME="Description" CONTENT="Elements is a free fantasy online game. Hundreds of creatures, spells, magic and artifacts to play with">
<META NAME="Keywords" CONTENT="fantasy, card, cards, elements, magic, spell, creature, entropy, fire, ice, earth, air, gravity, time, darkness, death, life, light, aether, deck, collectible, dragon, zanzarino">
I don't know how much it would help but we could add terms such as "electrum", or "otyugh", or "maxwell's demon". These are uncommon or "niche" terms but it could help guarantee that EtG would be at the top of those searches.
